Description
P108
Maximum operating speed n3
*
When the speed-dependent current limitation is in use, the maximum speed
FDS
which is defined by the selection of the actual speed source as set in P083,
must be entered in this parameter:
(G161)
When P083=1 (analog tacho):
Speed at which a tacho voltage as set in P741 is reached
When P083=2 (pulse encoder):
Same value as maximum speed set in P143
When P083=3 (operation without tacho):
Speed at which EMF as set in P115 is reached
P109
Control word for speed-dependent current limitation
*
0
Speed-dependent current limitation is deactivated
FDS
1
Speed-dependent current limitation is activated
(G161)
P110
Armature circuit resistance
FDS
This parameter is set automatically during the optimization run for precontrol
(G162)
and current controller (armature and field) (P051=25).
(G165)
P111
Armature circuit inductance
FDS
This parameter is set automatically during the optimization run for precontrol
(G162)
and current controller (armature and field) (P051=25).
(G165)
P112
Field circuit resistance
FDS
This parameter is set automatically during the optimization run for precontrol
(G166)
and current controller (armature and field) (P051=25).
P113
Continuous current factor torque control / current control
*
This parameter defines the current to be permitted as a continuous current
FDS
2
by the I
t motor monitoring function without activation of alarm message
A037 or fault message F037.
This current is the product of calculation P113 * P100.
P114
Thermal time constant of motor
(see Section 9.15)

t monitoring deactivated
P115
EMF at maximum speed in operation without tachometer
This parameter is used to adjust the speed in cases where the internal
FDS
actual EMF value is applied as the actual speed value. P115 defines the
EMF which corresponds to maximum speed as a percentage of P078.001.
(G151)
P117
Control word for field characteristic
*
0
No valid field characteristic has yet been recorded
FDS
1
Valid field characteristic (P118 to P139 valid)
The parameter is set automatically during the field-weakening optimization
run (P051=27).
P118
Rated EMF value
EMF that is reached with a full field (according to parameter P102) and a
FDS
speed as set in parameter P119.
The parameter is set automatically during the field-weakening optimization
(G165)
run (P051=27) and specifies in this case the setpoint EMF in the field-
weakening range.
Note:
As regards the closed-loop field-weakening control, only the ratio between
P118 and P119 is relevant. The EMF setpoint in the field-weakening range
is determined by (P101 – P100 * P110). When the setting in P100, P101 or
P110 is changed subsequently, the field-weakening optimization run need
not be repeated. However, P118 then no longer defines the setpoint EMF in
the field-weakening range.
When the setting in parameter P102 is changed subsequently, the field-
weakening optimization run must be repeated, the same applies if the
maximum speed setting is subsequently re-adjusted.
